The update file is transferred to the switc h asynchronously from either an INADS
host or a personal comput er (PC) using the XMODEM protocol.

Remote download

Remote users can dial into the switch b y either using the “ca ll” command (from
an INADS host) or by dialing the switc h directly with a modem. O nce the
connection has been estab lished, the user logs into the s witch as a remote
system access terminal (SAT) using the inads log in.
NOTE:
Only the INADS and INIT logins have the necessary p ermission to send an
update file to the switch.

wait..." displays on the screen.
After completing som e initialization, "Please start file
transmission now..." displays.
